Most Commercial Roofs Can Be Repaired or Restored - Not Replaced
The roofing industry pushes costly tear-offs you may not need. We assess honestly, repair when possible, restore with our RainArmor cool-roof system when your roof needs more, and replace only when it's genuinely necessary.
Repair. Restore. Replace Only When Necessary.
We service every commercial roof type, and we'll tell you honestly what yours actually needs.

What Our Clients Say
Trusted by property owners and facility managers across California
"Very professional company specializing in acrylic roof coating. Jeff was extremely thorough, easy to communicate with, and made the entire process smooth from start to finish. The work was done right, on time, and with great attention to detail."
"I was impressed from start to finish. Quoting process was fair and in-depth with lots of photos. When we got our first big rain storm recently, no leaks! Thank you HP for giving me peace of mind!"
"After trying two other companies without success, they were the ones who finally got it right. The job was completed on time, communication was clear, and the quality of the work was excellent."
"HP Roofing PRO did a great job on our office building. They fixed the leak properly, and the cool roof has made our offices much more comfortable in the summer by lowering the indoor temperature."
"I received a prompt answer, a thorough quote, full legal disclosures, and no hidden costs. I valued the crew supervisor's regular updates. They left the job site spotless and acted with the utmost professionalism."
"We had a leak at our warehouse in which we hired a few roofers to try and fix. None of them were able to find the fix. When we hired HP Roofing, they guaranteed us that they would fix the problem."
